Cardiac PET in Setting of prior CABG
Wael Jaber, MD

Challenges with prior CABG :
1. Anatomic “landmarks” of various coronary arteries are not applicable
2. Segmental defects that are not contiguous
3. ECG changes that are not specific for ischemia
4. Abnormal septal motion
5. Flows and flow reserves are not well validated
6. Correlation with angiographic results may be challenging
